Reactive Energy Compensation
Whether the Reactive Power originates from the local or external grid, as well as whether it is caused by the energy supplier or the end user, it has a strong negative impact on the capacity and efficiency of electrical systems, resulting in losses and increased costs.

Phase Balancing
Phase imbalance in a three-phase system is a condition in which one or more of the voltages between the lines in the three-phase system are inconsistent. Three-phase energy systems and equipment are designed to operate in balanced phases, with voltages between phases usually varying by several volts, but a difference of more than 1% can be detrimental to motors and equipment.

Harmonics Pollution:
The Silent Killer in the power grid

Harmonics Pollution is present in every electrical installation, and the greater it is, the greater the risks to the installation and equipment. In installations with a large number of non-linear loads included, the risk of high harmonic pollution is extremely high. Harmonics are also a cause of additional reactive energy.

Starting Current Limitation
For most electrical devices, the starting currents are significantly higher than the rated ones. Although these processes are short-lived, they can increase electricity costs for businesses. Depending on the tariff used, energy companies may charge a monthly fee based on the maximum energy consumption, not the nominal one. The excess can be up to 30% of the monthly electricity costs.
Short-term compensation for voltage sags
In power supply systems, the voltage may drop relative to the nominal value. This could lead to electric motors and other devices consuming currents exceeding the rated value, which can lead to their damage and reduced efficiency.
Smoothing Transition Processes
Transients that lead to short-term surpluses (usually several milliseconds) of currents and voltages relative to nominal values may be due to external and / or internal causes. Such causes can be lightning strikes, switching power substations, switching loads. Voltage changes as a result of transients can reach from a few volts to tens of kilovolts, while current surges can reach tens of Kiloamperes.

Complete Reactive Power Compensation
Real Time Phase Balancing
Harmonics Filtering

AESS SLAVA contains a meter of network parameters, controller, switching and control unit, switchable cosine phase and interphase capacitors, iterative transformers, controllable harmonic filter, which are part of the modules for reactive power compensation, high voltage harmonic compensation filtering and balancing the phasses.

After switching on the AESS according to the controller's program, the reactive power in each phase is analysed. If such is detected, signals are given to turn on the cosine capacitors until the reactive power is fully compensated. At the same time, the harmonic composition of the network is analysed and switching commands are generated for the controlled harmonic filter.

It is important to note that, unlike other filter devices on the market, SLAVA controlled harmonic filters automatically adapt their settings to changes in the harmonic composition of the mains voltage (for example, due to the inclusion of newly acquired powerful equipment with non-linear valve converter with variable angle on), and this harmonic suppression may exceed 80%.

After completing the harmonic filtering, the controller generates commands to control the banks of the cosine capacitors separately in each of the phases (a major difference to the usual group control in the capacitor blocks). At the same time, in order to exclude the possibility of subsequent resonance (in the circuit - cosine capacitors - inductive elements of the network) and to avoid overloading the cosine capacitors, the controller evaluates the signal coming from the harmonic signal analyser and if necessary, generates a command to connect three-dimensional cosine capacitors to clear the parasitic resonance frequencies.

The banks of the cosine capacitors are connected for each of the phases in the AESS through an iterative transformer, which provides their additional protection against overload, both in voltage and current.

In order to protect the cosine capacitors, they are connected at the moment of residual voltage in the capacitor, determined by its previous state and the current mains voltage.

Providing versatile protection for cosine capacitors in the AESS allows to reduce their overall size and to increase the number of possible switching steps, which significantly increases the accuracy of reactive power compensation compared to modern controllable capacitor units.

The elimination of the phase imbalance in the AESS is provided by a block of "interphase" capacitors. The block of "interphase" capacitors works in such a way that when the phase (linear) voltages of the network are unbalanced, the zero point of the capacitor bank is shifted, which in turn leads to a change in the position of the capacitor current vectors and their values. As a result, the current vector of the capacitor bank connected to the "overloaded" phase decreases, and the angle between it and the load current vector of the respective phase increases, which leads to a decrease in the corresponding mains current.

The current vector of the capacitor bank connected to the "underloaded" phase increases, and the angle between it and the load current vector decreases, which leads to an increase in the mains current of this phase.

In this way the values of the currents in the phases of the network are aligned, as a result of which the phase and line voltages of the network are equalised.

It should be noted that, unlike the solution with the inclusion of a balancing transformer (or voltage stabilisers), with the AESS the connection and installation are done in parallel, without interruption of the grid, which significantly increases the reliability.

In addition to all this, AESS SLAVA provides additional functions - protection against short-term sags and swells, reduction of inrush currents, as well as reduction of transients in case of lightning or powerful switching in electrical networks.

So far, our experience with AESS SLAVA shows that utilising it in industrial enterprises systems leads to energy savings of over 15%.
